在HDevelop中

dev_update_off()

read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray(Image,Image1)
*将RGB图像转换为灰度图像

threshold (Image1, Region, 200, 230)
dilation_rectangle1 (Region, RegionDilation, 11, 11)
*矩形膨胀
*参数1：膨胀区域
*输出区域
*参数3和参数4：结构元的宽和高-->决定哪个方向膨胀



get_image_size (Image1, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(Region)
dev_open_window(10,100,Width, Height,'black',WindowHandle1)
dev_display(RegionDilation)

 

 

在QtCreator中

    HObject  ho_Image, ho_Image1, ho_Region, ho_RegionDilation;
    HTuple  hv_Width, hv_Height, hv_WindowHandle;
    HTuple  hv_WindowHandle1;

    ReadImage(&ho_Image, "D:/bb/tu/1.jpg");
    Rgb1ToGray(ho_Image, &ho_Image1);
    //将RGB图像转换为灰度图像

    Threshold(ho_Image1, &ho_Region, 200, 230);
    DilationRectangle1(ho_Region, &ho_RegionDilation, 11, 11);
    //矩形膨胀
    //参数1：膨胀区域
    //输出区域
    //参数3和参数4：结构元的宽和高-->决定哪个方向膨胀



    GetImageSize(ho_Image1, &hv_Width, &hv_Height);
    SetWindowAttr("background_color","black");
    OpenWindow(10,10,hv_Width,hv_Height,0,"visible","",&hv_WindowHandle);
    HDevWindowStack::Push(hv_WindowHandle);
    if (HDevWindowStack::IsOpen())
      DispObj(ho_Region, HDevWindowStack::GetActive());
    SetWindowAttr("background_color","black");
    OpenWindow(10,100,hv_Width,hv_Height,0,"visible","",&hv_WindowHandle1);
    HDevWindowStack::Push(hv_WindowHandle1);
    if (HDevWindowStack::IsOpen())
      DispObj(ho_RegionDilation, HDevWindowStack::GetActive());
